Hi there,

I want to run FATFS example but I got this error ?

========================

nfo> app: FATFS example started.
                                             

nfo> app: Initializing disk 0 (SDC)...
                                       

rror> app: ERROR 1 [NRF_ERROR_SVC_HANDLER_MISSING] at ..\..\..\main.c:135
    

 at: 0x000024C3

How can I rectify this ?

Thanks

Hi, 

Are you using SDK 17.1.0? Do you use nRF52840DK or the custom board?

Do you modify the example? If so, what is that?

What is the function returned the error?

Hi Amanda,

Thanks for the reply,

I'm using : nRF5_SDK_17.0.2_d674dde SDK,

I don't modify the example only changing the port adapting to my custom board, it's working with DK board,

and with custom board it's working with external module, but not working with on board microsd connnector

it's returning error from :

 if (disk_state)
    {
              APP_ERROR_CHECK(disk_state); // Rixtronix LAB 18 Nov 21
        NRF_LOG_INFO("Disk initialization failed.");
              
        return;
    }

the function is fatfs_example

I put pull up resistors on CS,SCK and MOSI, still the same issue...

From logic analyzer, CH0=CS, CH1=SCK, CH2=MISO CH3=MOSI, that's only init and then fail....

Port continuity test :

Any clues ? thanks

Hi, 

RixtronixLAB said:

it's working with DK board,

Do you mean the same modified code and the same SD card can work with DK?
Is the SD card formatted (FAT32 or FAT)?
What is the flash size on the SD card?

What is the function at main.c:135? Is it "APP_ERROR_CHECK(disk_state); // Rixtronix LAB 18 Nov 21"? 
What is the value "disk_state" has in main.c at the point when the message is printed:"Disk initialization failed."?
(Compare it to the values in DRESULT in the diskio.h file and see if you get any information from that.)

Maybe take a look at these cases if they can help:
